Why is my DURASTAR DRAD09F1A Air Conditioner not cooling properly?
- CChristina PattersonAug 4, 2025
Several factors can cause poor cooling. The temperature setting might be too high, so try lowering it. The air filter or heat exchanger could be dirty, requiring cleaning. Obstructions in the air inlet or outlet should be removed after turning the unit off. Ensure doors and windows are closed, and reduce heat from sunlight by closing curtains. Low refrigerant levels, due to leaks or long-term use, require checking for leaks and topping off the refrigerant. Also, reduce the number of heat sources in the room.
